This is a picture of the N scale car and the finished HON30 gondola.
I first cut the sides from the N scale car, which is the only thing I used from the original car. I built the underframe from brass so the car would have enough weight, and the ends were built from styrene shapes.
NEXT: the TANK CAR
Starting with this N scale car, I took it apart and built....
J&N #2
These are the parts I used to build the basic car. After drilling out the riveted on trucks, the car comes apart easily with a single screw. The frame of the N scale car was too small for HON30 and way to light. I needed to add weight and size to frame and tried out several ideas including brass, styrene and wood.
The tank had slots in it, and I trimmed wood to fit in those slots to be chocks to hold the tank on the flat car.

I trimmed, filed and sanded all the molded on details except the rivets.
I carved off the original dome and added a piece of 3/8" tube for the man-way. I also turned some steel bar stock I had laying around to fit in the tank for added weight. Even with all this added weight, finished, it only weighted in at 1.4 oz.
To add maximum weight, epoxied brass bars in slots in the underframe. I decided to epoxy styrene all around the underframe to give me a 7' width and a reasonable looking length.
Here is the bottom of the underframe with the styrene added and the cast on moulding marks removed.
I filed the top side flat so the wood deck would fit tight.
I glued scribed wood to the underframe and trimmed to fit.
I painted the car, added a brake wheel, couplers and decals.
Then a little weathering and dullcoat for a finished look.

I used the underframe left over from the gondola and some other parts to make
The frame would be too light unless weight was added. I soldered brass bar stock to the sides and ends to give me the needed weight, width and length.
It took a while, even with a 200 watt soldering gun.
I stained the deck using the Pat Harriman method; I used Prismacolor markers.
I have gotta quit spending some much item on detail you can only see when the car is upside down! I used Grandt Line under body brake detail and stake pockets.
I did not figure the stake pockets into the width, so the car ended up about 6" wider than I would have liked, but I do like the way it turned out. This car weighs in at 1.5 oz. Considering it is about 4" long, that's not bad for a flat car.
I have dozens of projects that are waiting on good weather so I can paint. I have primed several projects, but I will have to wait until the weather warms up to do the finish painting.
Pretty neat. I model the 3" Montana Southern as it might have become had the rails not been pulled up circa 1940. Some original equipment, some that *might have been*, so your efforts are inspirational for me. Oh, and I model using N gauge track [9mm] but on a scale of 3mm=1", so my setup is NOT HOn30. I have no idea what it might be called, but I've got pretty much the same truck challenges that HOn30 modeers do.
